[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] In related technologies, existing elastic latex belts are typically made by splicing and extruding latex filaments. Specifically, several parallel latex filaments are extruded through equipment to fuse them together and form a latex belt. Currently, splicing machines are used to extrude latex filaments. These machines have multiple pressure rollers that simultaneously extrude and stably transport the latex filaments. However, the gap between the two rollers in the pressure roller device determines the outer diameter of the latex filaments. Currently, it is difficult to adjust the roller gap, requiring manual adjustment with tools for each operation, which is cumbersome and results in low production efficiency.

[0033] To solve the above problems, refer to Figure 1 In a first aspect embodiment of this utility model, an adjustment device is provided, installed on the machine base 100 of a thread-jointing machine. The adjustment device includes a support platform 101, a pressure roller 104, and a roller shaft 107. Multiple fixedly installed support platforms 101 are provided on the machine base 100 along its length. The roller shaft 107 is pivotally connected to the machine base 100 and passes through the multiple support platforms 101. A pressure roller 104 is pivotally connected between two adjacent support platforms 101. It is understood that during production, latex filaments pass through the gap between the pressure roller 104 and the roller shaft 107, and the position of the pressure roller 104 can be adjusted, thereby adjusting the thickness of the latex filaments by adjusting the size of the gap.

[0034] Reference Figure 2 and Figure 3It is understood that the support platform 101 is equipped with an adjuster 110, which includes a handle 111, a base 112, and a movable pin 113. The base 112 is fixedly installed on the top of the support platform 101, and the handle 111 is threadedly connected to the base 112. A first spring 114 is located between the handle 111 and the movable pin 113. Simultaneously, the pressure roller 104 is pivotally connected to the support platform 101. The support platform 101 is equipped with a second spring 102 supporting the end of the movable pin 113. The first spring 114 and the second spring 102 are arranged opposite to each other. It is understood that rotating the handle 111 can adjust the distance between the handle 111 and the movable pin 113, thereby changing the degree of compression of the first spring 114, adjusting the elastic force of the first spring 114, and thus adjusting the distance between the pressure roller 104 and the roller shaft 107. This allows for quick adjustment of the gap without the need for tools, facilitating the adjustment of the outer diameter of the latex filament and improving production efficiency.

[0035] Understandably, when the handle 111 is turned and the first spring 114 is compressed, the elastic force of the first spring 114 increases, and the first spring 114 can push the movable pin 113 to compress the second spring 102, thereby reducing the distance between the pressure roller 104 and the roller shaft 107, and increasing the pressure on the latex filament located between the pressure roller 104 and the roller shaft 107, thus reducing the outer diameter of the latex filament.

[0036] Reference Figure 3It is understood that the base 112 includes a mounting part 115 and an adjusting section 116. The mounting part 115 is fixedly connected to the top of the support platform 101. The adjusting section 116 extends upward from the mounting part 115. The outer peripheral wall of the adjusting section 116 has threads. The inner peripheral wall of the handle 111 is threadedly connected to the outer peripheral wall of the adjusting section 116. One end of the first spring 114 abuts against the inner end face of the handle 111, and the other end abuts against the movable pin 113, thereby ensuring that the elastic force of the first spring 114 can be adjusted when the handle 111 is rotated. Furthermore, a thrust bearing 117 is provided between the handle 111 and the first spring 114, which can reduce the frictional resistance between the handle 111 and the first spring 114 during rotation, making adjustment easier. Further, a guide bolt 119 is provided at the end of the handle 111 away from the pressure roller 104. The guide bolt 119 is inserted into the thrust bearing 117, and the first spring 114 is wrapped around the outer periphery of the guide bolt 119, which can prevent the thrust bearing 117 from shifting during installation. Understandably, the movable pin 113 has a guide portion 118 located within the base 112, and the first spring 114 is wrapped around the outer periphery of the guide portion 118, thereby preventing the first spring 114 from shifting during compression and facilitating the positioning of the first spring 114 during installation. Furthermore, the movable pin 113 has a limiting portion 120 extending radially outward, the bottom wall of the first spring 114 pressing against the limiting portion 120, and the limiting portion 120 abutting against the end wall of the base 112, thereby preventing the movable pin 113 from dislodging from the base 112.

[0037] Reference Figure 3 and Figure 4 It is understood that the support platform 101 is provided with a limiting groove 103, the pressure roller 104 has a support shaft 105, the support shaft 105 is inserted into the limiting groove 103, the movable pin 113 can extend out of the base 112 and press against the top wall of the support shaft 105, and the second spring 102 can support the bottom wall of the support shaft 105. Furthermore, the radial sides of the support shaft 105 have planes, which can abut against the side walls of the limiting groove 103, thereby enabling the support shaft 105 to move up and down stably. Furthermore, the pressure roller 104 is provided with limiting blocks 106 on both sides along the axial direction. The outer diameter of the limiting blocks 106 is larger than the outer diameter of the support shaft 105. The end of the limiting blocks 106 has a preset gap with the side wall of the support platform 101. On the one hand, it can prevent the support platform 101 from continuously rubbing against the limiting blocks 106 when the pressure roller 104 rotates, or prevent the limiting blocks 106 from continuously rubbing against the pressure roller 104. On the other hand, the limiting blocks 106 can prevent the pressure roller 104 from moving more than a preset distance along the axial direction, thereby ensuring the stable rotation of the pressure roller 104 and helping to ensure the stability of the wire feeding process.

[0038] In a second aspect of this utility model, a root-jointing machine is provided, including the aforementioned adjusting device. It is understood that the root-jointing machine includes all the technical features of the adjusting device; therefore, the root-jointing machine at least incorporates all the beneficial effects of the adjusting device.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
